Willett Family Estate 4 Year Cask Strength is a bold, undiluted bourbon poured at Grappa in Queen Anne, Seattle, where it brings a touch of Kentucky fire to a Mediterranean table.

About the Distillery

Willett Distillery is a family-owned operation in Bardstown, Kentucky, often called the heart of bourbon country. The Kulsveen family distills, ages, and bottles on the estate, with fifth-generation whiskey maker Drew Kulsveen overseeing the small-batch program. Released across rotating batches, this expression has earned a devoted following among collectors for its hand-built, personal character.

Style & Mash Bill

This is a cask strength, small-batch Kentucky straight bourbon, bottled without dilution at barrel proof. Each batch blends two of Willett’s house recipes — a traditional bourbon mash centered on corn sweetness and a higher-rye mash that adds spice, structure, and aromatic lift. Because it is bottled at full strength batch by batch, the exact proof varies; we recommend asking your server for the bottle currently open.

Tasting Notes

Expect a rich, concentrated pour: caramel, vanilla, and brown sugar layered with baking spice, toasted oak, and a warm rye snap. The undiluted strength gives it a long, glowing finish that softens beautifully with a few drops of water or a single cube of ice.

What to Pair It With

The bourbon’s sweetness and spice are a natural match for our American Wagyu Steaks, where the char and marbling meet the whiskey’s oak. It also stands up to the savory depth of our Sicilian Meatballs, and finishes the evening alongside the Flourless Chocolate Cake. Explore the full dine-in menu for more.

How It’s Served at Grappa

Poured neat or on the rocks at $23. Given its cask strength, we are happy to serve it with a splash of water to open up the aromatics.
